D 'Steam-waxmelting apparatus, by means of -which the wax is melted out of thehoneycombs are, known. Most devices ofthis klnd,

particularly those employed in operations on,

a smallscale have ,considerable disadvantage lori account of the inadequate yield 1n wax, as

l i @together with the wax the honey combscon- `tain considerable quantities of other substances vsuch for instance as cocoons `w1th which Athe cells are lined and constituents which interfere with the free .drawing olf of the fluid wax. Further as regards absence of danger and other matters the known devices need improvement in many respects.

In the presept invention the disadvantages mentioned above'are'obviated, in consequence of the particular construction of the'appara' tus, the latter beingA adapted to the special.

characteristics of the material to be dealt with namely, honey-combs. A

In .the construction of the apparatus, the -following fundamental ideas were adopted, 1. The .wax broughteto a molten state must be able totrickle from the. crude mass by the shortest path froms'its original positlonsothat hindrance to the lowing of the wax is avoided. .2. The melting of the crude mass must be effected on a horizontal base o'as largea surace as possible in order that it may not be necessaryffor the'mass of raw material tof be packed to any considerable depth-a condition which would stop the outflow of the wax.A The crude'V mass-should restas loosely as possiblt on-its support. a l

, 3. The support must be formed wlth numerous small holes in order that the fluid wax may be able topercolate-at all ponts',"whilst the' fine-grain residues on the contrary are `held back, \Further it'- must be possible lfor the support to be quickly and easillyv moved t e crudeV from outside (rotated),whereby l mass is again loosened and-brought intopther positions and a new way opened forithe re- 4 mainingwax-whicl-has notyet escaped.

4, The' crude mass must be subjected to steam over as large as possible apsurface .and a .permeated therewith in order-to .accelerate the melting process.v s .i d.

5. The'apparatusmust be capableof being considerable steam pressure should not arise, 'the steam must. rather low away freely.

employed easily and safely, the openin' of the '.same, as well as the stirring loi? the cru emass during the melting process should be avoided as the hot residues cause an unpleasantodour, f

` Fig. 3 Aa longitudinal view of the melting' drum.

` In Figs. 1 and '2, a is a steam boiler to be l partly filled with water. This boiler has a '70 heating bottom a. To this boiler is firmly .connecteda tubular melting kettle b lwhich 1s partially sunk in the steam boiler a. At the right hand end the melting kettle b is furnished with .a closing cover bbut on the left hand end with a conical tubular opening. n. In the melting kettle b is mounted to rotate the melting drum c with a closing coverc and this drum takes the form of a wide tube L or cylinder and serves for receiving thecrude or melted mass.

In consequence of the horizontal mountingl and the tubular form of this drum the entire lowerhalf of the drum is on the one hand made serviceable for the melted material contained half the diameter'of the drum to flow .through at any place, in order to be able to pass out oi the'drum; on' the other hand the melted 9o mass is spreadout and elongated horizontally lto avoid any considerable depthof material, whereby. any appreciable pressure ofthe up-y per on the lower layers is, avoided. On the left hand end ofthe melting drum c a pin m is firmly I; connected therewith. This pin runs through the tubular opening n into' the open "fair and is there provided with a boring e for the purposel of receiving a. rotary lever 7c.

With this lever 7c the melting drum can be 10o turned (rotated) to the right and left.. Thev melting kettle b is furnished at the right and f z y left slightly below the axial horizontal plane through said drum with openings f (as see Figs. 1 and2) through which the steam flows ,105 out of the steam boiler a and into the melting Q' The tube g inFigs. 1 and'2 serves for fillingV the steam-boiler a with water. --The small holes i in the melting drum o (see Figs, 2 im.

and 3) allow the fluid wax-to pass out of the same into the kettle b. h is a discharging channel firmly connected with the ,bottom ofv the melting kettle b and communicating with the drum c through openings o, and running tothe left, and terminatin in an extension It outsidel of the steam boi er having a discharge opening hf allowing the wax andthe steam to pass out of the apparatus.

The action' of the apparatus. is as follows:

- The melting drum c'is filled with crude material by first removing the end-covers b and 0 of the kettle b and drum c', the steam e boiler a partly filled with water and theheating bottom a exposed to the fire. The steam generated lows through the openings f in the a melting kettle b, heats the melting drum from all sides, passes through'the openings into the melting drum c, completely permeates the I nel'ting mass and through the heat causes the wax container in the crude mass to melt.

The fluid wax now trickles out of the crude mass,`leaves the melting drum .cthrough the openings i, then passes through the openings o into the discharging channel Irwhich is` somewhat inclined toward one end and passes out of the apparatus through the discharge lopening h simultaneously with the steam.

Since the wax, as explained above, does not flow freely from the comb, wax residue remains therein when the fused mass is allowed to stand.- In order 'to recover .this last trace of wax, that is,to obtainl a complete lyield, the position of .the comb'is changed periodically by rotating the drum. This rotation ofthe melting-drum is t repeateduntil passes ,out of h". f i Iclailm'- v v Wax melting apparatus for honeycombs includinef a boiler, Vra horizontall -no further wax er portion ug plane -thou extending into said boiler, havsteam kettle" bein in communication with said boiler throng perforations arranged in `the sides of Asaid 'common wallat points ad? jacenttheline of junctionof the sidewall o f the boiler with said steam kettle, a channel shaped member secured beneath' the botdisposed 40' steam kettle above said boiler having its .loW- A' to'about the horizontal median ing its wal in common with said boiler, said tom of said steam kettle, subtending the lowtermost portion thereof and incli'nmg downwardly toward one end, terminating Aoutf side said boiler, the wallof said steam kettle4 being formed with perforations communicating with the channel defined by said"channel vshaped member, said' steam kettle havin a permanent wall at one end and a remova le lid-at the other, Va bearing provided in .said premanent wall and-a per orated wax receivlng drum having a trunnionat one end adaptedto `be received in said bearing, the other tend of said drum resting rotatably against a yond said bearing, t
